The accelerated aging process is based on a common approach that assumes that the rate of aging increases by a factor of&nbsp; , where &nbsp;is the temperature increment. However, with the life data obtained from this empirical method is difficult to do inferences about reliability. This paper presents an accelerated destructive degradation test using thermal stress to obtain degradation data directly relates reliability to critical performance characteristic, which is the tensile strength in the intravascular catheter tip considered as a critical concern in patients’ safety. The degradation data model is given by a stochastic Wiener process with the drift parameter being represented as Arrhenius function. The parameters of the Wiener process and Arrhenius function are estimated using maximum likelihood; these parameters are used to estimate the first-passage time (time to failure) distribution when the intravascular catheters degradation path reaches a tensile strength critical value in each thermal stress level. Based on this, a complete product reliability assessment is performed and presented.</p> Kimberly Esqueda Hernández Luis Alberto Rodríguez-Picón Luis Carlos Méndez-González Roberto Romero-López Copyright (c) 2022 Kimberly Esqueda Hernández, Luis Alberto Rodríguez-Picón, Luis Carlos Méndez-González, Roberto Romero-López http://creativecommons.org/licenses/by/4.0 2022-06-15 2022-06-15 43 2 24 38 Comparison of Accuracy of Color Spaces in Cell Features Classification in Images of Leukemia types ALL and MM http://rmib.com.mx/index.php/rmib/article/view/1254 <p>This study presents a methodology for identifying the color space that provides the best performance in an image processing application. When measurements are performed without selecting the appropriate color model, the accuracy of the results is considerably altered. It is significant in computation, mainly when a diagnostic is based on stained cell microscopy images. This work shows how the proper selection of the color model provides better characterization in two types of cancer, acute lymphoid leukemia, and multiple myeloma. The methodology uses images from a public database. First, the nuclei are segmented, and then statistical moments are calculated for class identification. After, a principal component analysis is performed to reduce the extracted features and identify the most significant ones. At last, the predictive model is evaluated using the k-nearest neighbor algorithm and a confusion matrix. For the images used, the results showed that the CIE L*a*b color space best characterized the analyzed cancer types with an average accuracy of 95.52%. With an accuracy of 91.81%, RGB and CMY spaces followed. HSI and HSV spaces had an accuracy of 87.86% and 89.39%, respectively, and the worst performer was grayscale with an accuracy of 55.56%.</p> Cinthia Espinoza Del Angel Aurora Femat-Diaz Copyright (c) 2022 Cinthia Espinoza Del Angel, Aurora Femat-Diaz http://creativecommons.org/licenses/by/4.0 2022-06-28 2022-06-28 43 2 39 52 Hydroxyapatite and Biopolymer Composites with Promising Biomedical Applications http://rmib.com.mx/index.php/rmib/article/view/1245 <p>The purpose of tissue engineering (regenerative medicine) is to develop materials that replace human tissue, having as main characteristics' biodegradability, biocompatibility, no toxicity, osteoconductivity, which lead to cell maturation and proliferation. Due to the importance of the development of this type of materials, several researchers have used biopolymers and calcium phosphate salts (hydroxyapatite) as composites to be used in this area as drug releases, scaffolds, implants, among others. Different biopolymers can be suitable for this type of application, in this work we have described the most widely used biopolymers for biomedical purposes, such as alginate, collagen, gellan gum, chitosan, and polylactic acid, in addition to a detailed description of hydroxyapatite, biopolymers, as well as biopolymer/hydroxyapatite composites, to highlight their potential and the most relevant characteristics of these materials.</p> Juanita Daria Flores Valdez Aidé Sáenz Galindo Claudia Magdalena López Badillo Adali Oliva Castañeda Facio Pablo Acuña Vazquez Copyright (c) 2022 Juanita Daria Flores Valdez, Aidé Sáenz Galindo, Claudia Magdalena López Badillo, Adali Oliva Castañeda Facio, Pablo Acuña Vazquez http://creativecommons.org/licenses/by/4.0 2022-05-25 2022-05-25 43 2 6 23
